custom domain verification
I know that it's required to change the DNS record to verify that the domain belongs to me. Is there any other way to do it (other email providers let users upload a html file with a security key)? I have my domain registered at one provider and hosted at another. My host does not allow edition of DNS records (apart from MX) of domains that are not registered there, whereas if I change the DNS at my registrar, it won't work as the main DNS is delegated. I would have to relocate my domain to my server host which for reasons that are not relevant, I cannot do.
Any help, ideas?
